All through the third day it rained hard, but on the fourth I and my detail were back on the job. We were making progress. By this time a path had been cut through to the palm grove and from it to the umbrella tree.

It was clear that a century ago the line of palms must have stretched farther down the hill, for now the nearest was at least fifty yards from the umbrella tree, instead of twelve as mentioned in the directions.

The only alternative to this was that the original umbrella tree had disappeared, and this I did not want to believe. At best one of the landmarks had gone.

We could go seven paces beyond the big tree, but "beyond" is a vague word, the point from which the measurement began having vanished.

Moreover, we encountered here another difficulty.

"Take a Be line from here thirty paces throu ye Forked Tree," we read on the chart, but the forked tree had apparently fallen and rotted long since. There were trees in the jungle, to be sure, but none of them were of sufficient age to have been in existence then.

The best I could do was to guess at the point seven paces beyond the umbrella tree and, using it as a center, draw a circle around it at thirty paces. Our machetes hacked a trail, and at one point of it we crossed the stump of a tree that had been in its day of some size.

The stump had rotted so that one could kick it to pieces with the heel of a boot. This might or might not be the remains of the forked tree, but since we were working on a chance, this struck us as a good one to try.

It was impossible to tell where the fork had been, but we made a guess at it and proceeded to follow directions.
